' STEAM-TRAP.

Applicat on filed December 31, 1914.

To all .er'hom it may concern Be it known that I, JOHN M. I-Iroems, a citizen of the United States of America, and resident of Youngstown, county of Mahoning, and State of Ohio, have invented certain new and useful Improvements in Steam- Traps, of which the following is a specification.

This invention relates to certain new and useful improvements in steam traps, and the primary object thereof is to provide a steam trap which eliminates the usual ball floats, levers, trunnions and exterior valves-of traps of this type and to also provide a discharge opening that may be of any desired capacity, though preferably of the same size as that of the inlet pipe.

In the drawings: Figure 1 is a vertical sectional view of the invention, showing the parts in balanced position; Fig. 2 is a similar view showing the parts in discharging position; and Fig. 3 is a sectional view taken on line 3-3, Fig. 2.

In proceeding in accordance with the present invention, a body or casing 1 is provided having a-fianged top 2 towhich latter a cover 3 is secured. A skirt 1 depends from the cover 3 into embracing relation to receptacle or bucket 5. A tubular member 6 is secured to the bottom of the bucket '5 by means of a nut 7 threaded over the member and abutting the. bucket bottom, and a valve S in the form of a ring surrounds the member 6 and abuts a shoulder 9 on the latter and also the under face of the bottom of the bucket so as to be clamped against and between the latter and the shoulder by turning of nut 7. The lower end of the member 6 is formed with a piston valve 10 which has a valve face 11 that is adapted to seat against a valve seat 12 on the lower end of a sleeve 13v projecting on the opposite faces of the bottom of the bucket. The upper end of sleeve 13 has a valve seat 14: for engagement valve 10 reciprocates.

Specification of Letters Patent.

Patented Oct. 12, 1915.

vseriaino.s'iaesa 1. Steam is led into the trap through a pipe low the base of the piston valve 10. The pipe 20 discharges into a circular pipe 22 havingdownwardlv facing openings or perforations.

In operation, su'tlicien-t water is held in the bucket 5 to seal the trap, balance of the bucket being maintained in the up position shown in Fig. 1 by the pressure of steam admitted through branch 21 into housing 15 and acting against the base of piston valve 10, the steam acting to support the valve 10 and associated or connected parts and the water in the bucket, the latter constituting one of the parts just mentioned. Overbalance of the trap will result inthe valve 10 with the bucket moving to the down position illustrated in Fig.2, causing communi-' cation between the bucket 5 and exhaust opening or discharge passage 17 through the ports 18 in the member 6 and allowing water from the bucket to discharge, until the steam again reestablishes the balance and restores the movable parts to up position.

From the above it will be apparent that virtually but one movable part is involved in the structure, namely, the bucket, member 6, piston valve 10, and valve 8, which may be considered as one, since these parts. are all rigidly' connected and to all intents and purposes :are literally an integralstructure.

WVhat is claimed is 1. In a steam trap, a body having an interior depending skirt, a circular perforated steam dischargepipe at the top of the body surrounding the skirt, a water bucket slidable within the skirt, a tubular member clepending fromthe bucket bottom, a housing 20, which has a branch 21 that discharges, into the bottom of housing 15 at a point bedepending from the bottom of the body and having a lateral discharge, a. piston valve a sleeve secured to the bottom of the body and projecting above and below said bottom and having valve seats on its ends the lower of which valve seats is for engagement with the piston valve, a valve connected to the bucket for engagement with the upper valve seat of the sleeve, said member having ports above the valve to communicate with the housin dischar e and means to su l steam to the circular pipe and to the housing below the plston valve. 7 2 Ina steam trap, a body, a housing depending from said body and having a lateral discharge passage, a water bucket within said body, a tubular member slidably disposed within said housing and depending from and opening into said bucket, said member being provided with ports for communicating with said discharge passage and having a closed bottom provided with an annular upwardly facing valve face, a sleeve secured to the bottom of the body and projecting above and below said bottom and having valve seats on its ends, the lower of said valve seats being designed to have said valve face seat thereon, said bucket having an annular downwardly facing valve face Copies of this patent may be obtained for provided on the under side thereof for seating upon the upper valve seat of said sleeve, a skirt depending from the top of said body into embracing relation to said bucket, means for conveying steam to the interior of said body outside said skirt, and means for conveying steam to the interior of the housing below the closed bottom of said tubular member. a

In testimony whereof, I afiix my signature in presence of two subscribing witnesses.
